Why I Can't forward syslog messages using the ip helper-address

Hi All,

I am trying to forward the syslog messages received by the serial interface of R1 to the syslog server connected to SW2, but I can not see any syslog messages on my server.R4 is forwarding the syslog messages to R1, that's why I configured the "logging 150.1.1.1" toward R1.
the condition is to use the ip helper-address, so I can not configure the simple logging command toward the server.

shouldn't the command ip helper-address forward the syslog messages to the address associated with it? maybe I am not able to do it because the syslog is reaching R1 an unicast, and the rule it must be all IP levle broadcast for the ip helper-address command to start work !

if this is case then how I will convert the syslog traffic to be broadcast then !

I will be thankful if you shed light on this issue

R4----R1-----SW2---SYSLOG SERVER(192.168.1.101)

R4
logging 150.1.1.1

R1
inter loopback 0
ip address 150.1.1.1

interface Serial0
 ip helper-address 192.168.1.101

ip forward-protocol udp syslog

SW2
interface fas1/0/48
no switchport
ip add 192.168.1.80 255.255.255.0
ip broadcast-address 192.168.1.255
